Practising previous year question papers is one of the best methods of preparation for the JEE Main exam. This helps students to figure out their weaker areas and thus concentrate on those topics. As far as Mathematics is concerned, practising previous year questions is very important. This helps students to improve their speed of solving problems. Thus they can be stress-free and more confident during the exam.

Previous year chapter wise questions help students to get an idea of what type of questions are asked from each chapter. Students can easily access ** JEE Main Mathematics Chapter Wise Question Papers **from our website. These are also available in PDF format for free. Practising these question papers helps to understand the question pattern, marking scheme and the difficulty level of questions from each chapter. Following are the list of the chapter wise question papers.

2. Practising these papers help students to assess their preparation level.

3. Find out weaker areas and work more on those topics.

4. Students will get a clear idea of the type of questions and marking scheme.

All solutions are prepared by BYJU’S subject experts. Chapter-wise questions with solutions will help students to clear their concepts and score more in IIT JEE examination. Also, students can easily refer to the previous questions asked in the JEE Main from each chapter. Solving previous year questions will help students to improve their score in the exam.

### Angle Measurement

An angle measure is the measure of the angle formed by the two rays or arms at a common vertex. Depending on whether the rotating ray moves anticlockwise or clockwise direction, an angle formed by a rotating ray is said to be positive or negative. The three systems for measuring angles are given below:

1. Sexagesimal system

2. Centesimal system

3. Circular system

### Circular system of Angle Measurement

This is also known as the radian system. The angle is measured in radian in this system.

A radian is an angle subtended at the centres of a circle by an arc, the whole length is equal to the radius of the circle. It is used instead of degrees. The numbers of radians in an angle subtended by an arc of the circle at the centres = arc/ radius.

Students are recommended to learn the topic clearly so that they can easily crack the JEE questions. As far as the JEE exam is concerned, ** angle measurement** is an important topic. Important conversions are given below. Students can expect 1 question related to this topic.

### Important conversions:

π radian = 180^{0}

1 radian = 180/π

1^{0} = (π/180) radian

π/2 radian = 90^{0}

π/6 Radian = 30^{0}

π/4 Radian = 45^{0}

π/3 Radian = 60^{0}^{}
